Hernandez v State Rail Authority of NSW

The case of Hernandez v State Rail Authority of NSW involved a worker who sought compensation for a range of medical treatments, including shoulder surgery, and ongoing management of hypertension, cardiac, and renal conditions. The worker alleged that these conditions arose from back injuries that had been accepted as compensable between 1973 and 1992. The matter was heard and determined by the NSW Supreme Court.

The primary legal issues before the court were whether the worker had successfully demonstrated a causal link between the accepted back injuries and the need for the contested treatments. The court had to weigh the medical evidence, particularly from the treating doctors, against the opinions of the qualified specialists who had assumed inaccurate medical histories in their assessments.

The court ultimately found that the worker had not proven a causal nexus between the accepted injuries and the need for the treatments, except in the case of the transient aggravations of hypertension. The court rejected the worker’s evidence regarding the onset of hypertension in favour of a more reliable medical history documented in a report. Additionally, the court considered the opinions of the specialists to be based on assumed inaccurate histories, and there was a lack of evidence from the treating doctors to support the claimed causal link.

The court's decision resulted in a finding that the worker was only entitled to compensation for the treatment of transient aggravations of hypertension, with all other claims for treatment being dismissed. The Supreme Court's reasoning was influenced by the precedents set in Paric v John Holland (Constructions) Pty Ltd and Ho v Powell, which were cited in the judgment to support the requirement for a clear causal link between the accepted injuries and the need for treatment.
